Be it knownv that I, LonIsL. MAYER, a" citizen of the United States v residing at -.Vale,.in thecounty of Butte, Stateof South the size thereof. The other end of each of the plates 14: is formed with'the parallel Dakota, have invented certain newand useful Improvements in Scraplngand Leveling Devices; and I do hereby declarerthefoh lowing to be a full, clear, and exact description of'the invention, such as, will enable others'skilled in thefartz-towhich it appertains to make and use the same.

This invention relates to improvements in land level-ere. l a r, The principal object of the invention; is .to

provide-a simple and efficient deviceiofzthis character which isparticularly adaptzedfor leveling land for irrigation purposes. andas: to-fill any adjacent depressions A still further object is to; provide novel means for controlling the above mentioned dispersion of the soil.

Other objects and: advantages be. 8:1 parent. from the following description; when taken in connection with the acqompanying drawings. 7 Y a In the drawings: Figure 1; isasid-e eleva- 1 tionof: my invention. -.Fig. 2 is; a top plan view. Fig; 3' is a detail? section on th'e line tion on the line 44 of Fig: 2'. li ig -iis anenlarged' detail plan viewof'a portion of the frame, illustrating the adjustment of 9 one of the scraper blades, the same being g aside-members lO and 11 are the obliquely arranged braces -3Q,and' secured within the partly broken away. Fig. 6 isa longit'udinal sectional View on theli ne 6-6 of Fig. 1.

Referring particularlgv' to the acaompany- I ing drawings, there is shown an elongated frame which includes the parallel side mem bers 10 and 11, the transverse membersl 2i and 13 which connect respectively the front and rear ends of the side bars, and the intermediate transverse connecting member 13.

Secured to the inner face of each of the side members 10 and 11 is alongitudinally ex tending plate 14, each of these plates having an elongated opening 15 which registers with a similar opening 16 formed in the side member. The upper and'lower edges of the plate 14: are bent so as to extend t0- scraper bar 20.

dents of this character a which will automatically transfer soil from the points-beirrglereliid so ward each other as indicated at 17 toprovidelguides'for a sliding controlling door or gate 18, said door orgate being arranged to be moved across the opening to regulate guiding flanges 19, and slidable vertically between these guiding flanges is a scraper bar- .20. This bar 20 extends transversely of the frame and-[is disposed slightly in advance of the-member 13 and in parallel relation therewith. Mountedon the member 13! arethevertically extending brackets 21 in which is mounted a rock shaft 22 provided on: its ends with the-forwardly ex- .tending arms 23, these arms being loosely connected to theeyes 24L carried bythe Rigidly mounted on the shaft. 22; is avertical lever 25 which is provided with apawl device 26 forengagement ;-,withi a-rack segment 27' also mounted on the 1 memberl32' The forward lower portion of the; scraperbar-20 has securedfthereto" a metal scraping blade 28. (plates '14 has extending across the: outer angle formed; by the forward of the flanges Each of a the with the bodyportion of the plate,' a bar orpin .29, the purpose of which will appear hereinafter. 7

moving the lever 25 backward or 'forward", the shaft '22 will be rocked in the brackets 21 and the arms .231forced, to move the scraper bar 20 up and" down between the guidii'rg flanges 19. Thus the said scraper bar'is capable of adjustment to pro- Ij'ect the scraper'blade 28 below the frame and in position tov act on the soil, or be drawn upwithin'theframe and out offconta-ct with the soil: a l 1 Connecting the end member 1 21 with the angle formed between the side member, and the brace is an angle plate 31. The forward end portion of this plate is a vertical flange 32,-and extending between this flange and the portion of the plate which is secured to the brace 30 is a pin 33. The portion of the plate 31, which is attached to the side member, is formed with a pair of vertically alining apertured ears 34, and mounted in these ears 1s a vertical shaft 35 which is formed with a central crank portion 36 and a handle portion 37, the latter being disposed on the upper end of the shaft. Seated within the angle of the plate 14 and flange 19 is the scraper bar 38, the opposite end of which is engaged with the plate 31 and against the flange 32. Each end of the bar .38 is formedv with the notches or kerfs 39 which receive the pins 29 and 33 respectively. The end of the bar which is engaged with the flange 31 is provided with a plate 40 which has a lateral flange at its outer end, this plate being disposed to-be engaged by'the crank portion 36 of the shaft when said shaft is turned into operative position. It will be noted that the crank portion, when moved into operative position engages the lateral flange of the plate so as to limitthe movement thereof.

so that it will be out of engagement with the ground, or the bar maybe entirely removed from the frame, and the bar 38 adjusted to the proper height and arranged to extend diagonally across the frame according to the side fromwhich the soil is to be delivered.

The sliding gate 18 at the delivery side of the frame is then moved to open'position,

and the frame drawn across the field by any suitable means. The soil whichis loosened by the scraper bar 38 will travel toward the rear end of the bar and be delivered through the opening 15 thereat. 'When it is desired the frame in the opposite direction. In this case the gate or door 18 which was open is then closed. and the other door opened.

When the device is used for filling ditches,

dead furrows and the like, the scraper bar" 20 is adjustedto the proper'distance below the frame and the bar 38 raised out of the way or removed entirely from the frame.

Particular attentionis called to the manner in which the bar 38 is adjustably held.

The distance between the flange 32 and the side bar is such that when the crank portion I 36 is thrown out of engagement with the bar, this end of the bar will have a considerable amount of play in a direction toward the side bar and away from the flange 32. This a causes the other end of the bar to be rocked and greatly facilitate the disengagement of the bar from the pin 29. The constant pressure of the soil against the bar, in the operationv of the ,device causes the bar to be wedged tightly against the pins, and by providing this amount of play, the operator is enabled to quickly and easily remove the bar without the necessity of the use of special tools.

Pivotally mounted on the sides, and'at the rear end portions of theside bars are the triangular plates 41, guides 42 straddling the plates, and serving to limit the swinging movements thereof. Each of the plates is provided with a plurality of openings 43 arranged in series concentric with For ordinary leveling, the bar 20 is raised corners of the members 41, when said members are swung downwardly, are arranged to bite into the soil so as to hold the frame against side movement, and against skidding. 1 I

What is claimed is:

1. A scraping and leveling device comprising a frame, a diagonally arranged removable scraper bar, the ends ofsaid bar.

being formed with pluralities ofnotches,

means carried by the frame for engagement 'in' the'notches at one end of the bar, and

'means carried by the frame for clamping engagement with the other end of the bar.

2. A scraping and leveling device comprising aframe, angle members carried by the frame, and formed with transverse webs, I

- a scraper bar having notches at its ends, in-

terchangeably. receiving the webs of certain of the angle members, and means carired by certainothers of the angle members for engagement with one end of the bar, for forcing said end of the bar into engagement with the last-named angle member, whereby both ends of the bar are held from vertical or lateral movement.

In testimony whereof, I aflix my signature, in the presence of two Witnesses.
